createFunction()

Creates a new function


    public
                    createFunction(string $call) : IQueryFunction

Attention: Column names inside the call have to be quoted before hand

Example: $qb = $conn->getQueryBuilder(); $qb->select($qb->createFunction('COUNT()')) ->from('users', 'u') echo $qb->getSQL(); // SELECT COUNT() FROM users u $qb = $conn->getQueryBuilder(); $qb->select($qb->createFunction('COUNT(column)')) ->from('users', 'u') echo $qb->getSQL(); // SELECT COUNT(column) FROM users u

Parameters

createNamedParameter()

Creates a new named parameter and bind the value $value to it.


    public
                    createNamedParameter(mixed $value[, self::PARAM_* $type = self::PARAM_STR ][, string $placeHolder = null ]) : IParameter

This method provides a shortcut for PDOStatement::bindValue when using prepared statements.

The parameter $value specifies the value that you want to bind. If $placeholder is not provided bindValue() will automatically create a placeholder for you. An automatic placeholder will be of the name ':dcValue1', ':dcValue2' etc.

For more information see

Example: $value = 2; $q->eq( 'id', $q->bindValue( $value ) ); $stmt = $q->executeQuery(); // executed with 'id = 2'

Parameters

$value : mixed
$type : self::PARAM_* = self::PARAM_STR
$placeHolder : string = null: The name to bind with. The string must start with a colon ':'.

Return values

IParameter

createParameter()

Creates a new parameter


    public
                    createParameter(string $name) : IParameter

Example: $qb = $conn->getQueryBuilder(); $qb->select('u.*') ->from('users', 'u') ->where('u.username = ' . $qb->createParameter('name')) ->setParameter('name', 'Bar', IQueryBuilder::PARAM_STR))

Parameters

$name : string

Return values

IParameter

    public
                    createPositionalParameter(mixed $value[, self::PARAM_* $type = self::PARAM_STR ]) : IParameter

Attention: If you are using positional parameters with the query builder you have to be very careful to bind all parameters in the order they appear in the SQL statement , otherwise they get bound in the wrong order which can lead to serious bugs in your code.

Example: $qb = $conn->getQueryBuilder(); $qb->select('u.*') ->from('users', 'u') ->where('u.username = ' . $qb->createPositionalParameter('Foo', IQueryBuilder::PARAM_STR)) ->orWhere('u.username = ' . $qb->createPositionalParameter('Bar', IQueryBuilder::PARAM_STR))

Parameters

$type : self::PARAM_* = self::PARAM_STR

Return values

IParameter

    $qb = $conn->getQueryBuilder()
        ->delete('users', 'u')
        ->where('u.id = :user_id');
        ->setParameter(':user_id', 1);
